In a TEA CO2 laser, the most important influence on  the discharge is the dissociation of dioxide carbon. By adding  assistant gases into the laser, the discharge characteristics are improved. In this paper, we have analysed and calculated the  dissociation rate of CO2 and made the theoretical analyses and  experimental researches of the influence of gases CO and H2 on  the discharge in detail.
